This is this special report from ABC news. I'm -- that's where New York with an ABC news digital special report on that George -- murder trial. In Sanford Florida defense. Having it's now second day and what we're looking that. Is a face time testimony of Halloween still -- -- and neighbor of George Zimmermann. This testimony. Coming after that offense -- a famed forensic pathologist on the stand today doctor -- -- my IO. Focusing on the gunshot wounds. That children on Martin an injury this season George government and it would join us now from outside the courtroom and -- reporters ABC's parent trustees Aaron thanks for joining us. I I want to ask you this Bob -- really on mr. -- mile the pathologist whose testimony backed -- Georgia Romans account. Of that night he sort of the markings. Of the bullet on trade on Martin's Fletcher show that trade on. Was on top of Zimmerman and leaned forward when he was shot explain a little bit about the impact of that testimony. Well it really goes to bolster George Simmons credibility or try to rehabilitated after a bruising. Prosecution case tried to rip it apart. And what doctor Vincent a mile this forensic pathologist did was say that the markings on -- on Martin's chest the that the trajectory of the bullet. Were all consistent with George -- account which is that save on Martin was on top of him and leaning over him. As George -- pulled the trigger and fired upward into his chest now on cross examination. The -- conceded to prosecutor Bernie Hillary under that. It also could have been -- save -- Martin was backing away and leave the there was no definitive conclusion. From the from the famed forensic pathologist. -- there was also a lot of -- in today's testimony on Georgia remains head injuries. How did the pathologists answer in that. This was some pain -- testimony taking jurors. Really inch -- -- from all over Jordan Zimmermann is headed up on the big projector screen. Was blown up image -- Simmons bloodied -- scabs and bruises and blood. All visible some jurors actually seem to have a little bit of difficulty just staring at it. And and at that point. The pathologist told the jury through the injuries and and crucially. And probably said that these injuries were severe or at least more severe. Then previous witnesses have indicated remember a pathologist testified to the state. That George -- injuries were minor insignificant. And said we'll hear. Doctor dimaio said gosh how many of us Bob -- head in our heads -- open a -- seem to indicate that this was a much more stunning. Type of injury and of course George Zimmermann is here to prove that he felt like his life was in danger and that's why he was justified in his use of deadly force. Every four let's go when asked what the prosecution's time with doctor -- on cross examination they were trying to obviously and you history that trade on Martin was on top of Zimmerman. In their exchange where the prosecution effective in making their point. Well they at least got him to concede that -- on Martin could have been backing away but it was a tough go this was. Pathologist who has testified before pat and a number of -- trials and so I think he's practiced in the art of cross examination. He wouldn't go too far afield although there was an odd exchange when doctor dimaio testified that. You could literally rip someone's heart out and they could still live. -- ten to fifteen seconds after walking and talking and he made this point. -- to help again bolstered George Zimmerman credibility remembers him and said that he was forced to a slave trade -- Martin's arms down. Even though Martin was found in his hands and a different position and he also testified. During police accounts that -- said something to him after the the fatal gunshot and so that the doctor gave a little bit of credibility to that. Bernie Hillary on of the prosecutor was a little incredulous saying you -- you can rip out my heart I could still be walking around and -- looked at his watch any time ten to fifteen seconds for the jury. It was a little bit goofy and it may have gone to cut into the credibility of the pathologist but nonetheless. Overall it seemed as if the doctor was there to say George -- was not -- this is -- credible guy and at least his account jives with. Plausible medical science. Very illustrated and visual point. All right ABC's -- diversity in Sanford -- Aaron thank you about -- what -- bring in. Prosecutor and a -- -- nickel oxy here earning -- exterior and NC thanks for being with us obviously connect you've been watching the the trial. They had a good day they put on a very powerful well qualified and polish -- witness. So when you listen to him certainly people came out of the direct examination of Dr. to mail saying wow is there a case -- but again. I'll take the other side of that because really what he said. Is that these wounds would be consistent. With what George Zimmermann said that is different than saying that he is a credible witness as the cross examination. And Bernie didn't Rhonda pointed out -- you can't say who followed who. You can't say that those wounds didn't come from them rolling around in a more evenly matched scuffle and things like that so. While he was a fantastic witness -- you -- for the defense because they put him on and he made good points. I think that the prosecution did his job I did their job I should say in cross examining him -- as a lot to work with now for. Be ended the trial their summation and most importantly what I looked -- is the best moment of the cross examination was when they show that picture of George Zimmermann they said. Look if he has all -- blood on his face after the -- to his nose wouldn't you expect if someone had their hand over his nose and mouth to be blood on their hands. And doctor. Very deal Rhonda took his time as he walked back to the witness stand and now as for affected he had -- Let me ask you about that because in YouTube he -- on the point that I wanted to get to next when you're saying -- and a professional that that he is obviously he brought up there. For his professional insight his opinion and his experience when you bring -- a forensic pathologist often times. You might lose the attention of the jury because they're looking for someone that is going to be brought up there as a witness. That can either offer some kind of. It was -- as you said he alive Tanzania this a doctor taking a stand people say oh lets you know let's just sit back in our seats -- get comfortable. -- united being I've tried it homicide exclusively for the last twelve years every case has had a medical examiner. And you take your witnesses -- you find them is really what they're talking about that. -- the jury as opposed to the witness himself -- sometimes you have people that. Don't perform well they did their job well there -- not great witnesses they don't. Speak as well they aren't as powerful as -- -- -- has he really -- altogether he certainly has the background. And I'm sure the prosecution wishes they had that sort of demeanor in their own medical examiner but because doctor -- didn't come off as. Well and certainly seemed to go far feel the time in his testimony. It doesn't mean that he didn't do the job well -- hand that he was. Cast with and that was conducting the autopsy of trade on Martin. There were some combative moments during last week's testimony when doctor -- had taken the stand not only with the defense but also with the judges well in some of the proceedings that were going not. I want to ask you then did the state change things up today by focusing suddenly on who started the fight. I thought that it was great today for the state because they started to do the type of thing I've been thinking about what it is that I was a prosecutor be saying -- -- and they started to get some of those points sound cross examination of doctor de Mayo. Well you know while you can tell us through the science if -- well medically it's George Simmons accounts consistent you can't tell us who followed bill -- doctor he said now. You can't tell us who started the fight you can't tell us who -- who first. You can't tell us most importantly here what was in George -- to mind at the time that he pulled out his gun and fired and those are just some of the questions our asked of him. That it wasn't so much the answer that was important but it was the question to start to get the jury thinking that you know what this isn't really a case about the forensics the forensics can. Show consistency -- inconsistency but you still could certainly have a conviction here. If it is that they don't find that George Zimmer was being honest and all his accounts and that at the moment the critical moment that he didn't believe he was about to die or be massively wounded. What do you read into the fact that the judge today delayed a decision on whether to allow that 3-D animation. Of the shooting into trial. It means -- -- certainly not discounting and that she's may well be considering putting an end and really what that is going to turn on in part is what it was that the expert used in creating. Their piece here. You know did they take any creative license because that they dead -- it's probably not coming in -- -- but if they use the pieces that are really on contrary evidence to put together. A video -- of this than she may well allow with a strong instruction to the jury. That is just taking different pieces of evidence and putting it in a visual context which I'm sure the prosecution will say is just but one of the different scenarios. And lastly is the jury in your mind at this point wondering why perhaps the state didn't put on an expert witness perhaps as powerful as. -- -- -- May -- but again -- -- you take your witnesses as you find them and again this with a Doctor Who was assigned to conduct the autopsy which really is not be crucial in determining factor in this case and I would as a prosecutor you don't want this to become a battle the expert. Doctor demand was a powerful defense witness but I think the prosecution and used them. To their own ends as well it's a -- had it with great witness today for the defense the prosecution still cannot use him. To make a point to summation to the jury again. Every teacher would -- to see witnesses just like doctor demand that are well spoken that are. Professionals if you well that really don't -- don't seem to go far afield but that isn't always what you get but it doesn't it shouldn't be with the case turns on in the end. All right and it's -- a glossy thank you for your time and you or your insight on day two for the defense. The defense saying that it expects in fact to wrap up its case tomorrow and we have a complete recap on abcnews.com. -- today's testimony and the entire trial. For now I'm -- that's our New York with the CBC news digital special report. This has been a special report from me.
